The water may be poured into the tunnel 9 in orderto replenish the tank with water. for slaking the carbid. A portion ofthe wall). adjacent to the bottom l has a vertical slot 16 thereinAwhich is cov-' ered by a box 17 secured to the exterior ot thewall, thebox having a neck portion 18 thereon extending upward a suitabledistance and secured to theexterior of the casing 3, the upper end ot'the neck preferably having a funnel 19 thereon. 'A guide 2O is securedAto the casing 3 ywithin the funnel and a guide 2l is secured totheinner side ofy the wall 2. A rod 22 extends throughthe guide 2O and hasa handle 23 on its upper end which when desired may rbe supported onfanarm24 that is pivotally supported in a bracket 25, Secured tothe casing3, and

- the rod may be lowered when the arm is swung away from beneath thehandle. The normally lower end of the rod 22, has a lateral arm 2Gthereon within the box 17 Vand a return rod 27 extends from the armupward through the guide 2l and has a cross-` bar 28 thereon which isprovided with aA downwardly extending linger 29 whichis in contact withthe inner side ot the wallv 2 behind a. vertical guide 30 on the wall. cThe slaking water may if desired be poured also' into. the unnell9, orthe tunnel may receive water for` washing out the residuum from tank. nThe yupper portion of the casing 3 has an .5; aperture'3l thereinprovided with a funnel 35 32, in order that theA sealing water or liquidmay be conveniently poured into the sealing compartment.v Anoutlet pipe33 is arranged adjacent tothe inner side ot the wall 2 and is supportedon an elbow 34 which is connected to a ldischarge pipe 35 extendingthrough and secured to the wall, the upper endr of the pipe 33.preferablyfhaving an* elbow 3G thereon to prevent moisture lfrom gas.

' The generator is provided with a safetyvalve which comprises anupright rpipe 37 supported by an elbow 38 adjacent to the inner side ofthe wall 2, the elbow being yconnected yto and supported by an escapepipe 39 which extends through and is secured to the wall 2. The-upperopen end of the pipe '37 is normally .closed agalnst the escape ofgas bymeans of a cap comprising y a tube 40 extending down over the pipe a 55` suitable distance, the tube havingfa head 41 closingits upper end,the lower end of the tube having a cylindrical shaped screen il securedthereto and extending about the pipe 37, the cap being elevated by meansof a chain 43 connected thereto when4 the gas` is generated in excess ofrequirements.

A gas-bell comprises a cylindrical shell t4 of suitable diametertofreely pass over the wall Aofl the tank and within.' the casing3, thelower end of the bell being open and imrtively andthe ends of'thevdownwardly extending ears 66 and G7 respecti-vely, providedrespectivelywith pivots "63. The plates 59 and 60 are maintained inparallelfrelation by means of thimbles 69 y and tie-rods 70. `aresupport-ed in the two plates 59 and 60 :tween the plates 6l andr 62.bodies 73 and 74 are mounted respectively mersed in water, as iscustomary in gas generators, the shell having a, conical top/l5 into themiddle Portion of which extends a cylindrical magazine for holding thecarbid, the magazine having a hopper shaped bottom 47 and a top 4S, thetop being provided with `a removable filling plug 49.

TheV yplates form arectangular discharge "chute (33 through which the carbid falls into the57 and 5S are mounted tank. The plates 59 and V60 have extensions t Geland 65,011 their lower portions respec extensions have Two pivot rods 7land`72 and extend from one to the rother of the plates at asuitablefdistance below the'plane of the lower end of the plates 6l and62 and somewhat farther apart than the space be- Two valve on the pivots`7l and 72 between the side plates 59 and 60 and extend upward to the'lower ends of the plates 61 and 62., the valves having curved upperworking faces 75 and Q76 respectively, which are adapted to close thechute or partially `open it. The valve bodiesv are provided at the upperportions thereof with pvot rods 77 and. 78 respectively, twostiff links7 9. and SObeing connected to the rod 77, vtwo similar links 81 and 82being connected to the rod 7S. The two plates 59 and 60 have verticalguide slots 83 and 8i therein,respectively, n tween thepivots 7l and 72.A pivot rod 85 extends through `and is guided in the two guide slots andis connected with all the links, and two operating rods 86 and 87 are fconnected at one end to the pvotrod 85.

An operating lever comprises two arms SS and 89 connected at oneend tothepivot 68, and a cross bar 90 connected to the opposite end' of the.arms. A pivot rod k91 is connected to the arms 'ofthe lever yand also tothe normally lower ends ot' the rods S6 and midway beisc lfil-Lithinible y92;.is' preferablyplaced ybe-j filled and refilled withcarbid, while the l suitable distance tiveenithetwo arms of theleverfandfsecured thereto by a tiero'd 93 so'that theflever' may `v `be,stopped in itsy yupward movement byij` the fthiin'blecoming in. contacty with the lower edges'of the side plates and @0in which position thevalve ,-,is'wide-open.

In order to prevent the carbidy from pack-1 f ing on the bottom of themagazine a suitable number of standards 95 are secured upon the bottomI7 and support a cone 96 at a 'above Lthe bottom.

In some cases n weight 97 on its lower l,end `composed of lead in orderto maintain the 'desired degree of pressure on the gas. y f

In practical use `the generating tank contains a suitable ,quantityfofwater as does also the sealing compartment, and normally the cross bar28 is depressed. The plug 49 is removed 'while thev magazine is beingfeed val-ve is closed. If it is desired to feed a quantity of carbid byhand or quickly generate the gas, the attendant raises the handle 23 andagain pushes it down vor may hold it up byvmevans of the arm 24.
